this requirement without the need for testing.
NOTE In this case, the support structure will determine the resistance to imposed forces.
4.4 Water permeability

Where required, the absence of holes shall be checked by visual inspection of the finished product.
4.5 Vapour and air permeability
As long as these products have no holes (as defects), they are air and vapour impermeable.
Where required, the absence of holes shall be checked by visual inspection of the finished product.
4.6 Dimensional change
The thermal expansion shall be taken into account in the change of dimensions of the product, where this
change may have an effect on the performance of the product, by stating the appropriate thermal expansion
coefficient.
The following thermal expansion coefficient shall be used:
−6 –1
— aluminium: 24 × 10 K ;
−6 –1
— copper: 16,8 × 10 K ;
−6 –1 −6 –1

unless the manufacturer demonstrates by appropriate means that more accurate values are applicable.
4.7 Dimensional tolerances
The dimensional tolerances specified for roof covering products in the applicable standard from the following:
EN 506, EN 508-1, EN 508-2 and EN 508-3, shall not be exceeded.
For other products, the tolerances declared shall be appropriate, due account being taken of any national
provisions in the country of use.

mass) and/or category of any coating(s) to enable users to select products which may be expected to provide
the required durability of the product having regard to the expected environment and/or exposure conditions
and feasibility of maintenance.
4.9 External fire performance

In the absence of European harmonized test methods, verification and declaration on release/content should be
done taking into account national provisions in the place of use.
